Abstract (en)
A system for treating an exhaust gas from a lean burn internal combustion engine comprises a NOx adsorber catalyst (NAC) and a downstream selective catalytic reduction (SCR) catalyst, wherein the SCR catalyst comprises a copper promoted small pore molecular sieve having a maximum ring size of eight tetrahedral atoms, wherein the system meters nitrogenous reductant into a flowing exhaust gas only when it is determined that the SCR catalyst is at above 100 °C.
